Both new 24:7 lenses darken and fade in a hurry, and they keep on changing after other brands' photochromic films stop working. 24:7 lenses in NXT® are also virtually shatterproof, with a lifetime warranty against breakage.

24:7 Contrast in NXT: If you are planning to wear your 7EYE glasses night and day or indoors and out, the 24:7 Contrast in NXT is the ticket.  It fades to a yellow tint for better visibility at night and in low light and darkens to a deep brown that improves contrast by cutting haze.  The inner lens is treated with an anti-fog coating for all weather performance.
